BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to curtains, and in particular to stage curtainsoften used in entertainment productions.

2. Description of the Related Art

Curtain retraction systems are known in the related art. Somenon-limiting examples include: U.S. Pat. Nos. 516,018, 1,084,781,1,407,248, 1,651,985, 1,894,833, 1,900,677, 2,002,268, 2,420,301,2,676,654, 3,075,805, 3,092,174, 3,141,497, 3,310,099, 4,062,519,4,828,003, 4,850,415, 4,919,186, 5,029,629, 5,092,382, 5,430,980,6,283,192, 6,736,184, 7,128,122, 7,287,570, 7,703,499; Great BritainPat. No. 190726231, and Japan Pat. Nos. 2002-078603 and 2005-049531.

Retracting a curtain is referred to as a “Kabuki drop” or “Kabukieffect” in the related art. A curtain cropping from a conventionalsystem can take several seconds to disappear, typically at least 4-6seconds. Conventional curtain drop or pull systems suffer from slowwithdrawal of the curtain from the audience's view. Conventional curtaindrop systems consistently suffer from slow disappearance speeds, andthus have a lesser dramatic effect.

Tube-shaped systems called “curtain sniffers” or “curtain sniffters” areknown in the related art. For example, a large 20-foot tube into which acurtain is pulled is known in the related art as a conventionalsniffter. Such tube-based sniffters can be used to contain a curtainafter it is dropped. Conventional tube systems in stage production rangefrom 20′ to 40′ in length, typically having a diameter of about 30″.Some tubes have a 90-degree elbow where the curtain is pulled intofirst, adding to the cumbersome size. Small tubes are less desirable dueto inability to fully withdraw a curtain. Conventional tube-basedcurtain withdrawal systems are typically bulky and thus difficult totransport, not fitting on a standard shipping pallet. Such systems canalso be difficult and cumbersome to set up and take down.

Some motorized curtains are known in the related art. Such curtains canbe opened or closed, typically along a rail. However, conventionalrail-based curtain systems do not permit removal of the curtain from thepath of the rail.

Sandbags and weights are also known in the related art. Weights areknown especially in curtain pulley systems. However, conventionalgravity-based approaches can be limited to the force generated by asandbag weight, in turn limiting curtain velocity. Some curtains areheavy and require a large force and thus numerous sandbags or weightswould be required by such conventions, which can be cumbersome ordangerous when seeking to rapidly pull a heavy curtain, or when seekingto pull a curtain in an unusual direction.

A horizontal pole from which to hang a curtain is also known in therelated art. In some lesser known vaudeville acts, the curtain was hungfrom a horizontal pole which attached to a sandbag; when the sandbagdropped, the pole shot out sideways to allow the curtain to then drop bythe weight of gravity, then lacking hanging support. However, suchapproaches can be disruptive or harmful.

Thus, it can be seen that there is a need to provide a system which canquickly move a heavy stage curtain in an instant, without dropping asandbag, without damaging the curtain so it can be reused, and which canbe transported on a standard shipping pallet. Further, it can be seenthat there is a need to pull a curtain far more rapidly thangravity-based mechanisms, particularly with larger or heavier curtains.Moreover, it can be seen that there is a need to more rapidly pull acurtain away from the floor after it has dropped. In addition, it can beseen that there is a need to provide a more far more compact, modularsystem to make a curtain disappear, while minimizing interference withother stage designs. Furthermore, it can be seen that drawing a curtainin an unconventional manner to reveal or what is behind a curtain canenhance dramatic effect from the audience's perspective. Finally, it canbe seen that there is a need to address all of the aforementionedissues, alone or in any combination.

SPECIFICS OF THE INVENTION

FIG. 1 illustrates an embodiment of the present invention. Curtain 100is shown in FIG. 1, with cord 102, eyelet 104, and ring 106.

Curtain 100 can be made of cloth, whether synthetic, natural, or acombination thereof. In an embodiment, curtain 100 is not a Venetianblind. In an embodiment, curtain 100 can serve as at least a partialdivider from a viewing angle to any position upon, above, or below astage (FIG. 3, Roman numeral I). Curtain 100 can be transparent, opaque,partially transparent, or partially opaque. Curtain 100 can further havea rigid component, by way of non-limiting illustration: rivets,grommets, rings, loops, hooks, or otherwise. Curtain 100 can fully or atleast partially obscure a portion of a stage of any object of personbetween a viewing area and a stage area. At least one curtain can beconnected to at least one release. Curtain 100 can drop from hanger 500.There can be an at least one curtain 100. A plurality of hangers 500 cansupport curtain 100 (FIG. 5). The present invention can be usedsingularly or in plural.

Cord 102 can be a length of cord, synthetic or natural, woven ornon-woven, metal or plastic chain, or any combination thereof. Cord 102can be attached to curtain 100. At least one cord 102 can be attached tocurtain 100. Cord 102 can be attached to curtain 100 at one end, and tospool 206 at the opposite end. Cord 102 can be wound via spool 206. Cord102 can be capable of being wrapped around spool 206. Cord 102 can beattached to spool 206. Cord 102 can be pulled by engine 200, thuspulling curtain 100. Cord 102 can be pulled into funnel 300. Cord 102can be around a spool 206 as cord 102 is pulled into funnel 300. Cord102 can thereby retract curtain 100. In an embodiment, cord 102 can becentrally attached to curtain 100 with respect to any orientation,preferably centrally across the horizontal axis while curtain 100 is ina hanging position. In an embodiment, cord 102 can be attached below themidpoint of the height of curtain 100. Cord 102 can be verticallycentered, horizontally centered, both vertically and horizontallycentered upon curtain, or in some possible embodiments, arbitrarilyconnected to any other place on curtain 100. Placement of cord 102 oncurtain 100 and overall placement of shell 202 and/or engine 200 withspool 206 can produce a desired direction into which curtain 100 can bepulled, thereby providing a range of options for visual presentationwhen curtain 100 is pulled. In an embodiment, cord 102 can be attachedto a lower portion of curtain 100, such that as the upper portion ofcurtain 100 falls, the lower portion can be pulled via cord 102. Pullingcurtain 100 can occur at any time before, during, or after release; insome preferred embodiments, pulling 602 can occur after release 600. Inan embodiment, cord 102 can be pulled by engine 200 (FIG. 2). Thepresence or absence of cord 102 does not preclude the presence orabsence of any other attachments to curtain 100. Cord 102 can beattached to a draped portion of curtain 100. In some possibleembodiments, cord 102 can be attached to eyelet 104 or ring 106. In anembodiment, cord 102 can be tied to curtain 100 via a loop attached tocurtain 100. In an embodiment, cord 102 can run through any number ofintermediate pulleys.

Eyelet 104 can be a negative space to facilitate hanging of curtain 100.Eyelet 104 can be absent or embedded in curtain. Eyelet 104 can be anopening, loop, hole, sleeve, or any portion of curtain 100 complementaryto hanger 500 or any intermediate component. Eyelet can be elliptical,rectangular, or irregular in shape. Eyelet 104 can be part of curtain100, or a loop attached to curtain 100. Eyelet 104 can have a border tohelp resist wear and tear on curtain 100. In some possible embodiments,eyelet 104 can facilitate attachment to hanger 500 without ring 106. Abenefit of eyelet 104 can be to provide negative space by which curtain100 can be attachable or releasable. In another embodiment, eyelet 104can be formed by a flap folded over attached on curtain 100, with ring106 in the eyelet 104; ring 106 can be attachable to hanger 500 viasolenoid 502 (FIG. 5).

Ring 106 can be a metal ring, hook, curved shape, or any rigid portionby which curtain 100 can be hung or otherwise complementary to hangingor releasing via hanger 500. Ring 106 need not be fully closed, and neednot be an elliptical loop. In an embodiment, ring 106 need not be fullyclosed initially to allow curtain 100 to be placed on ring 106, afterwhich ring 106 can be physically closed or overlapped so as to bettersecure curtain 100. Ring 106 can be absent. Eyelet 104 and ring 106 canbe absent. Ring 106 need not be present. However, in embodiments wherering 106 is present, ring 106 can be pulled along with curtain if ringis the attachment to hanger 500. A benefit of ring 106 can be to providea cleaner, more definitive release mechanism in conjunction with hanger500.

FIG. 2 illustrates a side view of an embodiment of the presentinvention. Engine 200 is shown in FIG. 2, with shell 202, spool driveaxis 204, spool 206, curtain 100, cord 102, eyelet 104, and ring 106.

Engine 200, in a preferred embodiment, can be an electrically poweredmotor. In a preferred embodiment, engine 200 can comprise an at leastfour-horsepower motor. Engine 200 can be used to impart a pulling forceinstead of the dropping of a sandbag. Engine 200 can have a motor driveaxis via spool drive axis 204 can impart torque. Engine 200 can beattached to cord 102 directly or indirectly, for example, via spooldrive axis 204 having spool 206 affixed thereto, where spool 206 canrotate when engine 200 causes spool drive axis 204 to rotate. Engine 200can rotatably pull curtain 100 via cord 102. By way of non-limitingillustration, engine 200 can be a five-horsepower engine. Engine 200 canpull cord 102. Engine 200 can generate power to pull cord 102. A benefitof engine 200 is to pull curtain 100 quickly, for example, beforecurtain 100 drops. Another benefit of engine 200 over a dropped weightcan be to more rapidly pull curtain 100 while mitigating the risk ofharm caused by a dropping weight or sandbag. Yet another benefit ofengine 200 can be to provide the capability of unwinding curtain 100 forreuse by slowly imparting reverse torque on spool 206. Engine 200 can betime-coded by a programmable logic controller (PLC) to execute variousspeeds, and can provide gradual increase and decrease in acceleration,for example, to affect spool 206. In a preferred embodiment, engine 200can be a model EBM3625T available from Baldor Electric Company of FortSmith, Ariz.; two motor drive sprockets 1214 can be SKU No. D50B12 fromMartin Sprocket & Gear Inc. of Arlington, Tex. and pushed tightly to theshaft shoulder on the engine 200 and chained to the spool drive axis 204via spool drive sprocket 4800; and a shaft collar 4604, SKU No. 6436K19on a 1.125″ diameter shaft of engine 200. In a preferred embodiment,engine 200 can have an engine case 7.875″ diameter, 8.656″ high, 10.168″wide, and 19.088″ long without the motor drive shaft, or 22.645″ longwith the motor drive shaft.

Engine 200 is also shown in FIGS. 42, 43, and 44.

Shell 202, in many embodiments, can be a three-dimensional structurewhich has volume, whether box or non-box shaped, having a frame or noframe. Shell 202 can have inner and outer surfaces. In a preferredembodiment, shell 202 can have frame 1400. Shell 202 can have one ormore openings allowing curtain 100 to be drawn into shell 202, forexample, via funnel 300 or rim 302. Shell 202 can enclose one or moreobjects, for example: engine 200, spool drive axis 204, spool 206,fabric protector 208. At least one opening of shell 202 can be formedwholly or partially by rim 302. Shell 202 can be on support II. In anembodiment, shell 202 can be above stage I. By way of non-limitingillustration, shell 202 can have rim 302 through which the cord can bepulled, without funnel 300. In most preferred embodiments, curtain 100is not directly retracted into shell 202 in box form, but rather via rim302 at the opening end of funnel 300. In an embodiment, shell 202 cansimply be a facade or a flat wall rather than an encompassing enclosure.Shell 202 can be obscure at least a portion of at least one element ofthe present invention from at least one viewing angle, wholly orpartially. It will be understood that a “shell” when used in referenceto the present invention shall mean a housing, compartment, enclosure,one or more flat surfaces, a curved surface, a surface having one ormore angles, whether or not the “shell” forms a closed structure aroundany object, thus providing a measure of protection or at least partialenclosure. By way of non-limiting illustration, shell 202 can protect:engine 200, spool drive axis 204, or spool 206. Shell 202 can protectspool drive axis 204, engine 200, and spool 206. In an embodiment,before curtain 100 is pulled, shell 202 can form a plane in anyorientation; shell 202 can have an opening through which cord 102 can bepulled, and curtain 100 can be on a side of the opening of shell 202—byway of non-limiting illustration, the opening formed by rim 302. On theopposite side of the plane formed by rim, there can be spool 206, thepulling side. In some embodiments, the pulling side can be inside shell202. Shell 202 can have acoustic treatment, insulation, or cushioning.Shell 202 can provide protection for engine 200 and spool 206 in theevent of impact and can reduce chances of interference with the presentinvention during a performance, by way of non-limiting illustration, onstage I, or in front of, adjacent to, or behind curtain 100. In apreferred embodiment, shell 202 can comprise a box shape and dimensionswhich can be loaded easily on a pallet. Shell 202 can have a separatecompartment to store funnel 300. Shell 202 can have wheels underneath,including but not limited to fabric protector 208 in wheel form. Wheelson shell 202 can serve to protect curtain 100 from tearing, whenportions of curtain 100 flap toward or upon shell 202 during rapidmovement; curtain 100 having momentum can touch upon wheels instead ofcorners of a box-shaped shell 202, or otherwise sharp portions of shell202. In some embodiments with wheels, a benefit of wheels can be toeasily roll shell 202 with engine 200 and spool 206 quickly andefficiently for production set-up. In an embodiment, shell 202 withwheels can be rolled to and from desired locations, by way ofnon-limiting illustration, off a pallet and onto a truck, then into aconcert hall and onto a stage below a truss, then off to another palleteasily loaded onto any mode of transportation, to travel via air, land,or sea. Further, shell 202 can have fabric draped past any sharpportions or corners of shell 202, thus further protecting curtain 100from tearing or damage. Shell 202 can be one or more pieces. Shell 202can have one or more compartments. In a preferred embodiment, shell 202can have a frame with supporting struts (FIGS. 14-19) and mounting holes2602 spaced in rig plates 2600 on top of shell 202. Mounting holes 2602can be used to attach to support II with various sizes, preferablyspaced at 12″ and 18″ intervals with wider sets of holes for any otherspacing. Shell 202 can comprise end frame 8100. In a preferredembodiment, fabric protector 208 can be four 5×2 black swivel castors onone side of shell 202, preferably underneath shell 202 such that funnel300 when removed can permit shell 202 to be rolled to another locationand quickly packed. In a possible embodiment, shell 202 can comprisefunnel 300. Shell 202 can at least be a wall. In a preferred embodiment,shell 202 can have a path formed by funnel 300, shield 1200, gap 5704,and guide 5600, through which curtain 100 can be moved onto spool 206.

Spool drive axis 204 can be attached to engine 200. Spool drive axis 204can be chained to a sprocket rotated by engine 200. By way ofnon-limiting illustration, spool drive axis 204 can use the forcegenerated by engine 200 to impart torque. Thus, rotation can be appliedto spool 206. Spool drive axis 204 can comprise at least one spool drivesprocket 4800 (FIGS. 12, 45, 46, 48). There can be a plurality of spooldrive sprockets 4800, preferably at least two. In a preferredembodiment, spool drive axis 204 can be chained to engine 200 via atleast one sprocket. Spool drive axis 204 can comprise a shaft, the shaftbeing keyed, with 1.175″ diameter×30.0″.

Spool 206 can be any rotatable volume, cylindrical or non-cylindrical.Spool 206 can comprise a first spool plate 5000 (FIGS. 50-52), with aplurality of spool struts 5300 transverse to the plane of spool plate5000 and connected to a parallel spool plate 5000. A benefit of spool206 can be to help avoid losing cord 102 or curtain 100 as it is pulledto be wound upon spool 206. Spool 206 can be motorized, for example, byengine 200. A benefit of spool is to gather cord 102 onto the spool 206when engine 200 pulls curtain 100, so that curtain 100 can be morecontrollably directed during and/or after pulling curtain 100 iscomplete. Spool 206 can have cord 102 attached thereto, such that whenspool 206 pulls cord 102, cord 102 can wrap around spool 206. Spool 206can even wrap curtain 100 since cord 102 is connected thereto. There canbe any number of intermediate connectors in conjunction with cord 102,such as a chain connected to cord 102 and spool 206. There can be anynumber of intermediate pulleys, or no pulleys. In embodiments wherefunnel 300 is present, spool 206 can receive cord 102 as rim 302 helpsgather cord 102 and subsequently curtain 100. In embodiments where spool206 is within shell 202, a benefit of having spool 206 within shell 202is to provide a compact, efficient setup and takedown. In a preferredembodiment, spool 206 can comprise two opposing spool plates 5300 with aplurality of spool struts 5300 between each of the spool plates 5300. Ina possible embodiment, spool 206 can rotate such that a large stagecurtain is spooled in less than three seconds. A benefit of the presentinvention can be to quickly pull curtain 100 faster than has been donebefore with conventional means, particularly with a heavier or largercurtain. In a preferred embodiment, funnel 300 can be 0.125″ aluminumshaped conically with a smaller opening having a 12.320″ diameter whichcan open into shell 202 and a larger opening at rim 302 having a 22.000″inner diameter, and the outer diameter of rim 302 being 26.000″ due toan aluminum tube formed at an opening of funnel 300, the opening beingthe larger opening; further, funnel attachments 6500 can be recessed0.983″ from the smaller opening, on the outer surface of funnel 300. Ina preferred embodiment, spool 206 can have spool plates 5000 spaced19.500″ between the inner portions of each spool plate 5000, each spoolplate being 0.250″ thick, the outer distance can be 20.000″.

Fabric protector 208 can be any non-sharp surface, metal or non-metal,fabric or non-fabric, wheel or non-wheel. A benefit of fabric protector208 can be to provide a surface upon which curtain 100 may touch whilebeing moved, but while touching upon fabric protector 208, curtain 100or cord 102 is less likely to be torn or snagged, or otherwisedamaged—thus enhancing reusability of curtain 100. By way ofnon-limiting illustration, fabric protector 208 can be a wheel, fabric,or a non-sharp corner. In an embodiment where shell 202 is box-shaped,fabric protector 208 can be a plurality of wheels on shell 202 each upona corner underneath shell 202. In experimentation, it was determinedthat having shell 202 with corners and no fabric protector 208 such aswheels can result in damage to curtain 100 or cord 102; thus, curtain100 or cord 102 may not be in suitable condition for reuse in suchinferior embodiments. Fabric protector 208 can help avoid curtain 100from ripping against shell 202, or from damaging components within shell202. Fabric protector can be inside shell, outside shell, or both. Insome embodiments where curtain 100 is pulled upward into funnel 300,shell 202 can have more than one type of fabric protector 208: at leastone wheel and a downwardly extending shroud extending below each wheelto provide further protection for curtain 100. In a preferredembodiment, velcro 1212 (FIG. 12) can be present along with fabricprotector 208 in the form of wheels.

FIG. 6 illustrates a method diagram of an embodiment of the presentinvention. Release curtain 600 is shown in FIG. 6, with pull curtain602, rotate spool 604, gather cord 606, obscure curtain 608. The arrowsshown in FIG. 6 are not to be construed as strictly necessary in theorder of operation. A non-limiting example can be where pulling 602occurs at the same time or even prior to release 600.

Release curtain 600 can be done by dropping curtain 100 from hanger 500.Release curtain 600 can be done by triggering hanger 500 or otherwisecausing curtain 100 to not be attached, hung, or otherwise fixed tohanger 500. Release curtain 600 can move cord 102 attached to a curtain100 into funnel 300 upon sending a signal from a remote control device.Release curtain 600 can be performed by activating engine 200, which canbe remotely triggerable. Release curtain 600 can be done at the sametime pulling 602 occurs.

Pull curtain 602 can be facilitated by having cord 102 attached tocurtain 100. Pulling 602 can be triggered by activating 504 engine 200to pull 602 curtain 100. In an embodiment, pulling curtain 602 can bedone such that curtain 100 moves faster than would otherwise occur dueto gravity. In a possible embodiment, curtain 100 can be pulled offhanger 500 directly without initial release 600. In some embodiments,curtain 100 can be pulled directly without cord 102.

Rotate spool 604 can be performed by clockwise or counterclockwiserotation of spool 206. Cord 102 or curtain 100 can be attached to spool206 while rotating 604. Spool 206 can have a handle to crank spool 206manually in the desired direction. Rotate curtain 604 can be done inshell 202. Rotate spool 604 can be accomplished by the force generatedby engine 200. Rotate spool 604 can occur when engine 200 initiates.Spool drive axis 204 can torque spool 206. In a preferred embodiment,rotate spool 604 can include moving the spool at high speeds. A numberof rotations per second can be known for a three-second timespan wherethe diameter of the spool is known, and where a given length of cord 102with attached curtain 100 is known. In a preferred embodiment, rotationsof spool 206 can be time-coded via PLC. PLC can be given a gentle start,full speed, gentle stop, with full stop. The dimensions of spool 206,cord 102, and curtain 100 can be known. Weight, speed, and length can beprogrammable via PLC. In a possible embodiment, known dimensions can bevalues in programmable variables, where the dimensions of a stage andthus curtain or cord length may also change. One having ordinary skillin the art would be able to understand how to program a PLC to rotatespool 604, by way of non-limiting illustration, to turn engine 200 on oroff; or to turn engine 200 on or off with a remote control having aswitch for activating a remote signal to be sent to control box 1204thus activating engine 200 to begin rotating spool 604. Based on thedisclosure of the present specification, one of ordinary skill in theart can understand how to perform rotate spool 604. In a possibleembodiment, simple programming code instructing the PLC to rotate spool206 can be encoded in a hardware chip, by way of non-limitingillustration, in control box 1204. Rotate spool 604 can be achievedwithout requiring one of ordinary skill in the art to produce complexhardware or software programming in some possible embodiments consistentwith the present invention.

Gather cord 606 can be performed by pulling curtain 100 via cord 102through a narrowing space, such as rim 302, and managing cord 102 sothat the cord does not go in any random direction but rather is directedby the narrowing space to be wound upon spool 206. Gather cord 606 canbe pulling cord 102 through rim 302, or into funnel 300. Curtain 100 canbe gathered in the same manner, as curtain 100 can be attached to cord102. In embodiments where cord 102 is absent, gather cord 606 caninstead refer to gathering curtain 100. In a preferred embodiment,gather cord 606 can be performed by having spool 206 which comprises aplurality of spool struts 5300 between two spool plates 5000, the plates5000 gathering curtain 100 onto the plurality of spool struts 5300,where guide 5600 further prevents spool 206 and curtain 100 fromreaching engine 200 or outer portions of shell 202; further, shield 1200can be within shell 202 and can provide a path to further gather 606 sothat once cord 102 and curtain 100 pass through funnel 300, cord 102 andcurtain 100 can be wound onto spool 206 with less risk of uncontrollablyflapping into undesirable areas of shell 202 in the process of beingspooled, for example, if slack occurs in mid-spooling but cord 102 andcurtain 100 may still have inertia resulting in misdirection, which canbe reduced by having more surfaces to direct curtain 100 onto spool 206.In a preferred embodiment, cord 102 can be wound around spool 206

Obscure curtain 608 can include partially or fully hiding curtain 100from sight, by way of non-limiting illustration, in a direction toward,past, or into shell 202, spool 206, funnel 300, or rim 302.

Inhale curtain 610 can be any combination of 600-608. Inhale curtain 610can be done by the pulling of curtain 100, for example, via cord 102,into funnel 300 or shell 202. In some possible embodiments, inhalecurtain 610 can lift curtain 100 above the stage I or higher than theheight of the bottom of the curtain. Curtain 100 can be lifted upontriggering an engine. Inhale curtain 610 can be done to a corner ofcurtain 100, outward away from stage I, downward, or any otherdirection. If curtain 100 is dividable or otherwise split into more thanone piece, Inhale curtain 610 can include multiple curtains 100 beingpulled in different directions, each into its respective funnel 300 orshell 202.

Position funnel 612 can be done by fixably setting funnel 300 at alocation into which curtain 100 can be pulled 606. The given position offunnel 300 can be, but need not be, above stage I. Positioning 612 canbe done by a support, pole, tower, bridge, cable-supported horizontaltruss rig with no underlying supports, stand, truss, or rig.

Hang curtain 614 can include preparing hanger 500 to releasably hangcurtain 100, for example, directly to curtain 100, via eyelet 104, orvia ring 106. Hang curtain 614 can include rotating solenoid 502 in aholding position such that the open portion of solenoid 502 does notpermit ring 106 to drop therefrom. In an embodiment, hanger 500 canpermit the hanging portion of solenoid 502 to be hangable out of a firsthole in hanger 500 and a second hole in hanger 500 into which the end ofthe hanging portion of solenoid 502 can be rotated, thus creating aclosed loop while curtain 100 is in hanging position. Solenoid 502 canthereby prevent ring 106 from inadvertently being released, untildesired. In an embodiment, spool 206 can be reversed manually by turningor cranking the spool or initiating reversal via engine 200 can aid inpreparing to hang curtain 614 for reuse of curtain 100. In anembodiment, hangers 500 can be lowered to permit reattachment of rings106 to solenoids 502.
